prooflayer-sdk

The official JavaScript/TypeScript SDK for ProofLayer — cryptographic proof of digital content authenticity.

Installation

npm install prooflayer-sdk

Quick Start

import { ProofLayer } from 'prooflayer-sdk'

const client = new ProofLayer({
  apiKey: 'pl_live_your_key_here',
  baseUrl: 'https://your-prooflayer-instance.com'
})

// Create a proof for a file
const proof = await client.proofs.create(file)
console.log('Proof ID:', proof.proofId)
console.log('AI Score:', proof.aiScore)
console.log('Blockchain TX:', proof.blockchainTxHash)

// Verify a file by re-uploading it
const result = await client.verify.byFile(file)
if (result.result === 'AUTHENTIC') {
  console.log('File is authentic!')
  console.log('Original proof:', result.proof?.proofId)
}

// Get proof by ID
const proof = await client.proofs.get('PL-A1B2C3D4')
console.log('Creator:', proof.creator.name)

API Reference

new ProofLayer(config)

| Option | Type | Required | Default | Description | |--------|------|----------|---------|-------------| | apiKey | string | Yes | — | Your pl_live_... API key | | baseUrl | string | No | https://prooflayer.com | API base URL | | timeout | number | No | 60000 | Request timeout in ms |

client.proofs.create(file, options?)

Create a proof certificate for a file. Returns: Promise<ProofResult>

client.proofs.get(proofId)

Get proof details by ID (format: PL-XXXXXXXX). Returns: Promise<ProofResult>

client.verify.byFile(file, options?)

Verify a file by computing and matching its hash. Returns: Promise<VerifyResult>

client.verify.byId(proofId)

Get and verify a proof by its ID. Returns: Promise<ProofResult>

Error Handling

import { ProofLayer, ProofLayerError } from 'prooflayer-sdk'

try {
  const proof = await client.proofs.create(file)
} catch (error) {
  if (error instanceof ProofLayerError) {
    console.error('Code:', error.code)
    console.error('Status:', error.status)
    console.error('Message:', error.message)
  }
}
